Viewing images on the windshield of the car is not exactly a new idea, but the technologies developed so far were concepts only designed for luxury models. The Navdy is a simple heads-up display (HUD) that projects notifications, apps, and driving directions directly from your smartphone to the windshield, guaranteeing to keep your eyes on the road.

The focus of this project is safe driving. The use of cell phones while driving is increasing accidents at an exponential rate worldwide. With Navdy, the driver can perform a series of tasks on their smartphone without taking getting distracted from the road or having to actually look at the device screen.

There are already systems that enable cellphone use by the driver through voice command, but the Navdy seems to do it masterfully. Besides projecting information to the driver, the device recognizes spoken commands and gestures. With this combination of features it allows the drive to answer calls, reply to messages, change songs, check the driving directions indicated on GPS, measure distances traveled and so on.

By its looks, you must have realized what makes Navdy be compatible with virtually any car: the device was designed to be simply attached to the dashboard and its see through HUD does not block the windshield. Furthermore, the device can even display information directly on the windshield of the car.

For the device to work, you must connect the Navdy into your car’s OBDII port. Besides providing energy, this type of connection also transfers information such as speed, current gear and if there are any mechanical problems.

It is clear that such a project has a few setbacks as well. The fixation to the dashboard needs to be strong enough to not come off in case of a collision, the gesture sensors must be fast so that no time-consuming movements would be necessary and the projected images must be clear for the driver to not get distracted trying to understand them.

But common sense should still apply: even with Navdy allowing the user to reply to a tweet, for example, it is still safer and more prudent to do so when not behind the wheel.

A map of every device connected to the Internet shows the wealthiest parts of the world flush with connections, while poor and sparsely populated parts of the world are blacked out — as well as a few head scratchers in between.

The map was created by John Matherly, founder of Shodan, a search engine that probes the Internet’s backend for connections to all sorts of devices from routers to refrigerators. Matherly said it took about five hours to ping every IP address on the Internet and store every positive response. It took another 12 hours to plot the responses on a heat map which glows bright orange in densely connected areas and blue and black in sparsely connected areas.

The United State and Western Europe are, not surprisingly, awash in connectivity. Africa and central Asia have islands of connectivity centered on urban areas. Then there are head-scratchers like Greenland…
